Empress Xuan of Qin had an affair with King Yiqu, and even had two sons was recorded in the history of Zheng, but there is no record of the outcome of the children born to Empress Xuan and King Yiqu in the history, if we analyze, we can still get a glimpse of the historical truth and get a general conclusion.
Empress Xuan was a concubine of King Huiwen of Qin, her mother country was the State of Chu, in 306 BC, after the death of King Huiwen of Qin, the king of the state of Qin Wu died in the army out of Luoyang, king of Qin Wu was very young, no son to inherit the throne, king wu of Qin's brother in Xianyang for the throne of the quarrel, and finally the zhao state king Zhao Wuling support, let the prince Ji who was a hostage in the zhao state returned to Xianyang, was established as the king of the state of Qin, known as the king of Qin Zhaoxiang.
King Zhaoxiang of Qin, with the help of his uncle Wei Ran, quickly pacified the opposition in the country and exiled all his brothers who were vying for the throne. In fact, behind King Zhaoxiang of Qin was his birth mother Empress Xuan of the Qi clan who was in control of the imperial government.
Empress Xuan can be said to be the first very famous female politician in Chinese history, and her personal ability is even comparable to that of Wu Zetian, the only female emperor in ancient China.
Empress Xuan's control of the government had a certain basis, on the one hand, her younger brother Wei Ran had always been the state of Qin, and her son King Zhaoxiang of Qin was never eager to take back power from her mother; on the other hand, Empress Xuan's strong political ability and ruling skills were on the other hand.
Yiqu was a very powerful nomadic people in the northwest region during the Warring States period, they were the part of the Xiongnu who later caused disaster to the Central Plains, and during the Zhou Dynasty, Yiqu had been harassing the Central Plains in the northwest and northwest, until the Qin state was strong, and the Yiqu did not relent.
The fornication between Empress Xuan and King Yiqu was actually a kind of political marriage, when King Wu of Qin had just died, And King Zhaoxiang of Qin had just succeeded to the throne, according to the situation of the State of Qin at that time, it was not easy to be able to calm the rebel forces within, and if the Yiqu tribe joined the siege of Qin by the five eastern kingdoms, then the State of Qin might be divided by the princes, and the country would not exist.
According to the official history, Empress Xuan had an affair with King Yiqu in 307 BC, when King Zhaoxiang of Qin had just succeeded to the throne, and King Yiqu came from the grassland to Xianyang to congratulate the King of Qin on his ascension to the throne, and Empress Xuan was in a political alliance purpose, having an affair with king Yiqu to stabilize the invasion of the qin state by the grassland tribes through the love of men and women.
Although Empress Xuan had a yiqu king, although it was an adulterous affair, but it was also well known to the whole country, it could be clearly recorded in the official historical data, and she did not care about what others said when she wanted to come to Empress Xuan, and later because the Yiqu tribe was increasingly threatening the Qin state, the Qin state hoped to cut the Yiqu in one fell swoop, and the first problem was to eliminate the Yiqu king. At this time, Empress Xuan had already given birth to two sons to King Yiqu.
Empress Xuan conspired with King Zhaoxiang of Qin to deceive King Yiqu into coming to Xianyang and killing him at Ganquan Palace, already in 272 BC.
So the question is, how old are their children? From the fornication to the death of King Yiqu, there was a period of 25 years in between, that is, the children of Empress Xuan and King Yiqu were at least adults. So what will happen to their children after king Yiqu is killed?
We can analyze from the character of Empress Xuan and the situation at that time, first of all, Empress Xuan was a straightforward and frank female politician, and since she did not care that the historian wrote her affair with the King of Yiqu into the history books, she did not care that others said that her two children.
From the perspective of motherhood, Empress Xuan is unlikely to let the Yiqu King take the two children to the grassland, which is not in line with the character of The Xuan empress, and more importantly, the Xuan Empress also needs two children as an emotional means to bind the Yiqu King. Imagine why Empress Xuan was able to "lure" the King of Yiqu when Yiqu and the Qin state were quite hostile in 25 years?
Could it be Empress Xuan's ageless countenance? This is not scientific, nor is it very realistic, there must be other reasons, maybe it is the cause of the child, if there is such a relationship, it is possible for the King of Yiqu to come to the Qin Kingdom to see Empress Xuan.
So what about the end of their children after killing the Queen of Yiqu? According to the tolerant policy of the State of Qin and the power of Empress Xuan at that time, no one in the State of Qin could do anything with the two adult children, but they were considered to be half-brothers of King Zhaoxiang of Qin, although they could not hold important official positions in the dynasty, but it was still possible to ensure the safety of their lives.
From the above analysis, the children of Empress Xuan and King Yiqu were even Qin people from birth, and even got the surname of the Qin royal family, but as an ordinary nobleman, they lived a bland life and did not leave the slightest record in the history books, because for them, their birth itself was a political transaction.
